Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick production equipment, in particular to a mixing device for a refractory brick press. Background Art

[0002] Refractory bricks, also known as firebricks, are refractory materials made from refractory clay or other refractory raw materials. Before entering the press for molding, the raw materials need to be mixed evenly in a mixing device. However, the mixed raw materials are slightly sticky, making them difficult to discharge from the mixing device.

[0003] A mullite refractory brick mixing device disclosed in Chinese patent CN220496160U utilizes the reverse rotation of the feeding screw and the stirring mechanism on the inner wall of the inner tank to uniformly mix the raw materials inside the inner tank. After the mixing is completed, when the material needs to be discharged, the rotating mechanism controls the rotation of the outer tank. The outer tank rotates until the opening of the inner tank is tilted downward, and the feeding screw pushes the raw materials in the inner tank out of the inner tank, making the discharge convenient. However, while solving the problem, the mullite refractory brick mixing device has the following defects:

[0004] The feeding screw is fixed to the inner wall of the inner tank. Therefore, when the inner tank rotates, the feeding screw rotates synchronously with the inner tank. Therefore, for a small amount of raw materials stuck on the inner wall of the inner tank, the feeding screw cannot play a role in conveying. Instead, it will affect the flow of raw materials, thereby affecting the efficiency of material discharge. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] To this end, one purpose of the present invention is to propose a mixing device for a refractory brick press, which aims to solve the problem that the feeding screw of the mullite refractory brick mixing device in the prior art cannot effectively transport a small amount of raw materials stuck to the inner wall of the inner tank, thereby affecting the feeding efficiency.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the present invention on one hand provides a mixing device for a refractory brick press, comprising a mixing tank, a feed port is opened on the top of the mixing tank, a discharge pipe is fixedly connected to the bottom of the mixing tank, a transmission shaft is rotatably connected inside the mixing tank, a motor is fixedly installed at the center of the top of the mixing tank, the output end of the motor is fixedly connected to the top of the transmission shaft, a plurality of stirring rods are fixedly connected to the outer surface of the transmission shaft, a spiral rod is fixedly connected to the bottom end of the transmission shaft, and a part of the spiral rod is inserted into the discharge pipe, a plurality of one-way bearings are fixedly installed on the outer surface of the transmission shaft, a cross bar is fixedly connected to the outer surface of the one-way bearing, a spiral plate is fixedly connected to the end of the cross bar away from the one-way bearing, an inclined rod is fixedly connected to the lower surface of the lowest cross bar, and a scraper is fixedly connected to the end of the inclined rod.

[0008] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0009] First, during discharging, the rotating screw rod can quickly transport the refractory brick raw materials in the mixing tank outward, and the transmission shaft can drive the spiral plate and scraper to rotate, which can quickly transport the refractory brick raw materials stuck to the inner wall of the mixing tank downward and into the discharge pipe. Therefore, for sticky refractory brick raw materials, it has the advantages of high discharge efficiency and clean and thorough discharge.

[0010] Secondly, the drive shaft rotates clockwise, driving the stirring rod to rotate and stir the refractory brick raw materials. In the process, the spiral rod can transport the refractory brick raw materials at the bottom of the mixing tank upward, so that the refractory brick raw materials below can be fully mixed with the refractory brick raw materials above. Moreover, a part of the spiral rod is inserted into the discharge pipe, which can avoid the problem that some raw materials in the discharge pipe cannot be fully mixed.

[0011] The third is the setting of the one-way bearing. During stirring, the transmission shaft will not drive the cross bar to rotate, so that the resistance of the refractory brick raw materials on the spiral plate will not be transmitted to the transmission shaft, thereby reducing the load of the motor, thereby driving the transmission shaft to maintain a higher speed and improving the mixing efficiency.

The motor 21 drives the stirring rods 22 on the surface of the transmission shaft 2 to rotate at a high speed, thereby stirring and mixing the refractory brick raw materials in the mixing tank 1. The bottom end of the transmission shaft 2 is fixedly connected with a screw rod 23. When the motor 21 drives the transmission shaft 2 to rotate clockwise, the stirring rods 22 stir the refractory brick raw materials, and the screw rods 23 convey the refractory brick raw materials upward, thereby conveying the refractory brick raw materials at the bottom of the mixing tank 1 upward, so that the refractory brick raw materials below are fully mixed with the refractory brick raw materials above, and the screw rods A portion of 23 is inserted into the discharge pipe 12. A plurality of one-way bearings 24 are fixedly installed on the outer surface of the transmission shaft 2. A cross bar 25 is fixedly connected to the outer surface of the one-way bearing 24. A spiral plate 26 is fixedly connected to the end of the cross bar 25 away from the one-way bearing 24. When the transmission shaft 2 rotates clockwise to stir the refractory brick raw materials, the one-way bearing 24 cannot drive the cross bar 25 to rotate. When the motor 21 drives the transmission shaft 2 to rotate counterclockwise, the transmission shaft 2 can drive the cross bar 25 to rotate through the one-way bearing 24, and the spiral plate 26 at the end of the cross bar 25 can scrape off the mixed material. The inner wall of the tank 1 is adhered with refractory brick raw materials, and the refractory brick raw materials on the inner wall of the mixing tank 1 can be transported downward, and the spiral rod 23 rotates counterclockwise to transport the refractory brick raw materials downward, so that the refractory brick raw materials can be discharged from the discharge pipe 12. The lower surface of the cross bar 25 at the bottom is fixedly connected with an inclined rod 27, and the end of the inclined rod 27 is fixedly connected with a scraper 28. The scraper 28 is spiral-shaped like the spiral plate 26, so that the scraper 28 can transport the refractory brick raw materials into the discharge pipe 12 while scraping off the refractory brick raw materials on the bottom wall of the mixing tank 1.

[0025] Specifically, a baffle 3 is hinged at the bottom of the discharge pipe 12 for blocking or opening the bottom of the discharge pipe 12. A support plate 31 is fixedly connected to the outer surface of the baffle 3. A positioning block 32 is fixedly connected to the top of the support plate 31. The positioning block 32 is hinged to the bottom of the outer surface of the discharge pipe 12. A first electric push rod 33 is hinged to the outer surface of the discharge pipe 12. The piston rod end of the first electric push rod 33 is hinged to the end of the support plate 31. Extending the first electric push rod 33 can push the support plate 31 to rotate around the positioning block 32, so that the baffle 3 blocks the bottom of the discharge pipe 12, and vice versa.

[0026] Example 2:

[0027] like Figure 1 and Figure 4 As shown, on the basis of Example 1, a Z-shaped block 5 is hinged at the bottom of the outer surface of the discharge pipe 12, and a connecting hole 53 is provided above the middle of the Z-shaped block 5. A pin is inserted into the connecting hole 53 and then hinged to the bottom of the outer surface of the discharge pipe 12. A connecting groove 51 is provided on the top of the Z-shaped block 5, and a second electric push rod 52 is hinged on the outer surface of the discharge pipe 12. The piston rod end of the second electric push rod 52 is hinged in the connecting groove 51. After the baffle 3 blocks the bottom of the discharge pipe 12, the second electric push rod 52 can be extended to make the Z-shaped block 5 hang on the bottom of the baffle 3, thereby reinforcing the baffle 3 to ensure sealing.

[0028] Example 3:

[0029] like Figure 1 and Figure 4 As shown, based on the first or second embodiment, a cover plate 4 is hinged at the feed port 11 on the top of the mixing tank 1. During the mixing process, the cover plate 4 is used to block the feed port 11 to prevent the powder from rising.

[0030] Specifically, one side of the top of the cover plate 4 is fixedly connected to a connecting block 41, and a circular hole 44 is opened on the connecting block 41. By using a pin shaft to insert into the circular hole 44, and then hinged to the mixing tank 1 through the pin shaft, the top of the connecting block 41 is fixedly connected to a connecting seat 42, and the top of the mixing tank 1 is hinged to a third electric push rod 43, and the piston rod end of the third electric push rod 43 is hinged inside the connecting seat 42. By extending the third electric push rod 43, the cover plate 4 can close the feed port 11. Conversely, the cover plate 4 can be opened, and refractory brick raw materials can be added to the mixing tank 1 through the feed port 11.

[0031] The working principle of the present invention is as follows: when in use, the cover plate 4 is opened by retracting the third electric push rod 43, and after the refractory brick raw materials are added into the mixing tank 1, the third electric push rod 43 is extended to close the feed port 11, and then the motor 21 is started to drive the transmission shaft 2 to rotate clockwise, so that the stirring rod 22 stirs and mixes the refractory brick raw materials, and the spiral rod 23 conveys the refractory brick raw materials below upward, so that the refractory brick raw materials below and above are fully mixed;

[0032] After the mixing is completed, the second electric push rod 52 is retracted to make the Z-shaped block 5 loosen the baffle 3, and then the first electric push rod 33 is retracted, the baffle 3 rotates to open the bottom of the discharge pipe 12, and then the motor 21 drives the transmission shaft 2 to rotate counterclockwise, and the screw rod 23 can quickly transport the refractory brick raw materials in the mixing tank 1 to the outside, and the transmission shaft 2 drives the spiral plate 26 and the scraper 28 to rotate through the one-way bearing 24, which can quickly transport the refractory brick raw materials stuck to the inner wall of the mixing tank 1 downward and into the discharge pipe 12. After the discharge is completed, the first electric push rod 33 is extended to make the baffle 3 close the bottom of the discharge pipe 12, and then the second electric push rod 52 is extended to make the Z-shaped block 5 reinforce the baffle 3, and then the third electric push rod 43 is retracted to open the feed port 11, and continue to add refractory brick raw materials.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. During discharging, the motor 21 drives the transmission shaft 2 to rotate counterclockwise, and the screw rod 23 can quickly transport the refractory brick raw materials in the mixing tank 1 outward, and the transmission shaft 2 drives the spiral plate 26 and the scraper 28 to rotate, which can quickly transport the refractory brick raw materials stuck to the inner wall of the mixing tank 1 downward and into the discharge pipe 12. Therefore, for the sticky refractory brick raw materials, it has the advantages of high discharging efficiency and clean and thorough discharging.

[0035] 2. By arranging a screw rod 23 at the bottom end of the transmission shaft 2, the motor 21 drives the transmission shaft 2 to rotate clockwise, so that the stirring rod 22 rotates at high speed. During the mixing process, the screw rod 23 can convey the refractory brick raw materials upward, thereby conveying the refractory brick raw materials at the bottom of the mixing tank 1 upward, so that the refractory brick raw materials below can be fully mixed with the refractory brick raw materials above, and a part of the screw rod 23 is inserted into the discharge pipe 12, which can avoid the problem that some raw materials in the discharge pipe 12 cannot be fully mixed.

[0036] 3. The cross bar 25 is connected to the surface of the transmission shaft 2 through the one-way bearing 24, so that during stirring, the transmission shaft 2 will not drive the cross bar 25 to rotate, so that the resistance of the refractory brick raw material on the spiral plate 26 will not be transmitted to the transmission shaft 2, thereby reducing the load of the motor 21, thereby being able to drive the transmission shaft 2 to maintain a higher speed, and improving the efficiency of mixing.

[0037] 4. The arrangement of the Z-shaped block 5 is such that when the baffle 3 blocks the bottom of the discharge pipe 12, the second electric push rod 52 is extended to allow the Z-shaped block 5 to hang on the bottom of the baffle 3, thereby reinforcing the baffle 3 and ensuring sealing.

[0038] 5. By hingedly connecting the cover plate 4 at the feed port 11, the feed port 11 can be blocked by the cover plate 4 during mixing, thereby preventing the powdery refractory brick raw materials from being blown up from the top and causing dust problems.
